"WebDefine "meiosis." Understanding: One of diploid nucleus divides by meiosis to produce four haploid nuclei. Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes.

WebJan 20, 2024 · A crossover may occur in this region. If so, when the chromosomes separate during anaphase I one of the chromatids will have a duplication and one will have a deletion. Ultimately, of the four cells produced by this meiosis, two will be normal, one will have a chromosome with extra genes, and one will have a chromosome missing some … WebCrossing over occurs in metaphase when all the chromosomes are aligned in the middle of the cell. Their close proximity allows crossing over to occur. Crossing over occurs in telophase right before the cells split since all the DNA and cell growth has occurred by this point. Crossing over does not occur in mitosis.
